Abstract

The invention relates to mining and is intended to mechanize the process of attaching the roof of mine workings with anchors. The purpose of the invention is to increase the reliability of the mechanism. The mechanism of rotation of the disk magazine of the anchor support device has a disk magazine (DM) 6 associated with a telescopic stop 2 by chain transmission for the anchor rods 7. A turret 10 is fixed to the stop using brackets 8, 9. The output link 15 is rigidly connected with the DM 6 chain drive. The input link 16 of the chain transmission has a freewheel device, made in the form of an overrunning clutch 17 with clips 18, 19. The outer clip 18 is made integral with the input link 16, the Inner sleeve 19 is rigidly fixed on the bracket 9 of the turret 10. During operation of the mechanism during the movement turrets 10 to DM 6 last rotated one step. In this case, the clutch 17 automatically operates and the torque transmits through the link 15 from the bracket 9 the turret 10 to the shaft 5 DM 6. 5 Il.

FIG. five

The invention relates to mining, in particular, to the construction of devices for mechanizing the process of attaching the roof of mine workings with anchors.

The purpose of the invention is to increase the reliability of the mechanism.

FIG. 1 shows a device for installation of anchor bolts, top view at the time of completion of the operation of capturing the next anchor from the disk magazine and its readiness to drill a hole; Fig. 2 is the same, top view at the time of completion of the operation for transferring the anchor rod from the magazine to the axis of the drilled hole; in FIG. 3, view A in FIG. 2; figure 4 - section bb in figure 2; Fig. 5 is a kinematic diagram of the mechanism for rotating the disk magazine.

The rotation mechanism of the disk magazine of the anchor support mounting device contains an arrow-shaped manipulator 1, on which a telescopic support 2 and a hydraulic jack 3 of rotation of the telescopic support 2 relative to the manipulator 1 are mounted. To the telescopic support 2 on one side are fixed brackets 4 on which are hinged the shaft 5 of the disk magazine 6, on two disks of which anchor rods 7 are fastened, for example, of screw type, on the other side to the stop 2 by means of the upper 8 and lower 9 brackets are hinged a turret 10 containing a drilling machine 11 mounted on one guide rail and a mounting mechanism 12 with floating lunettes 13. The rotation drive of the turret 10 serves a hydraulic jack 14, the stem of which is pivotally connected to the upper bracket 8 of the turrets 10, and the cylinder with a telescopic abutment 2 In the lower part of the disk magazine 6 on its shaft 5 the output link 15 of the chain transmission is rigidly fixed, for example, in the form of an asterisk, and in the lower part of the telescopic support 2 on the bracket 9 of the turret 10 its input link 16 is placed in the form of an asterisk, equipped with This is provided by the overrunning clutch 17, the outer cage 18 of which is integral with the input link 16, and the inner clutch 19 is rigidly fixed to the bracket 9 of the turret 10. The overrunning clutch 17 is installed with the ability to provide turning the magazine 6 by one step only in the period of movement of the turret 10 along towards the store 6.

The rotation mechanism works as follows.

With the arrow of the arrow-shaped manipulator 1 and the hydraulic jack 3, the device is installed under the attachment point. The telescopic abutment 2 extends into the exposed surface of the excavation.

In this case, the turret 10 is in the position for drilling the bore-hole (FIG. 1), and the next anchor bar 7 of the disk magazine 6 to be installed is gripped by floating lunettes 13 of the anchor-setting mechanism 12.

A hole is drilled by the boring machine 11 and retracted upon completion of the drilling to the starting position. The hydraulic jack 14 is turned on, in the result the turret 10 rotates around the telescopic abutment 2 in the hinges of the brackets 8 and 9 until the axis of the drilled hole coincides with the axis of the anchor rod 7 located in the floating lunettes 13 of the anchor-setting mechanism 12, the rotation of the turrets 10 is not accompanied by the movement of the magazine 6, when the freewheel 17 is open. After the anchor rod 7 is transferred from the disk magazine 6 to the axis of the hole, the anchor rod 7 is screwed into the previously drilled hole of the anchor mounting mechanism 12, and the floating lunes 13 do not interfere with the rotation of the anchor rod as if the anchor rod 7 was screwed into the hole, and when you withdraw it to its original position. When the installation of the anchor 7 is completed, the jack 14 is turned on, and the turret 10 rotates towards the disk magazine 6, which in turn leads to the automatic actuation of the overrunning clutch 17 and the possibility of transmitting torque to the shaft 5 of the disk magazine 6 via the output link 15 transmissions from the bottom bracket 9 of the turret 10. At the end of the stroke of the turret 10, the disk magazine 6 is moved one step, with the result that the anchor rod 7 meets the floating lunettes 13 and seizes it last. Subsequently, the cycle for installing anchor rods is repeated, for which the device is moved to the next place of attachment of the excavation with the arrow-shaped manipulator 1.
